EGG-WASHER.

Specification of Letters Patent. 7 Patented Sept; 192(1 Applicationfiled March 27, 1920. Serial No. 369,405.

To all whom it may concern Improvements in- Egg-VVashers, of which Be itknown that I, GUILronD' MoCRAY, a citizen of the United States, residinin Tomales, in the county of Marin and tate'of California, have inventednew and useful the following is'a specification.

This invention relates to an egg washerv which is designed to enableeggs to be washed quickly and easily so as to render the samemoresalable and also more appe tizing. a i

It is the object of this invention to produce a machine of thischaracter which will permit of thoroughly. cleaning any dirt which maybe on the eggs by the use of comparatively little efiort and power andenable this to be accomplished without materially. increasing the costof the eggs.

4 In the'accompanyi ng drawings:

Figure 1 is a top plan view ofone form of machine embodying myinvention. Fig. 2 is a fragmentary vertical section of the same taken online 22, Fig. 1. Fig. 3 is a horizontal section taken on line 3-3, Fig.4. Fig. 4 is a fragmentary vertical section, on an enlarged scale, takenon line' H, Fig. l.

Similar characters of reference refer to like parts throughout theseveral views.

Although this machine may be organized in various ways so as to permitone or more operators to, work at'the same time, thatshown in thedrawings is so constructed as to permit two operators to work on oppo-'site sides of the table and each operator" is capable of cleaning twoeggs at a time, so

as to utilize both hands to-the best advanout of engagement with thecleaning 'orwashing devices which are arranged below thetable top.Theupper side of the table top is preferably covered with a sheet 14 ofmetal forthe purpose of protecting the same against undue wear 'and'also enable the same to be cleaned more easily.

-Below each'of the openings 12 in the table top is arranged one of thewashing or cleaning devices or units, which is constructed in accordancewith my invention, and as the several cleaning or washing devices arealike in construction and operation, the following description of onejofthem will applyto all of them:

15 represents a bowl or hollow head which is mounted to rotate about avertical axis,

below. one of the openings 12 in the .table .top, which bowl-may be ofany suitable shape but, as shown in Figs. 2 and/l, may

an-upright hollow shaft 19,'which is socured at its upper end to theoutlet nipple 18 by means of acoupling sleeve 20 so that the .shaftis'axially in line with the axis of the bowl. This shaft is journaled ina pair of bearings 21 arranged one above the other and formed on adepending bracket 22 which is secured to the'underside of the adjacentpart of the main frame 10. The downward motion of this shaft in thesebearings is limited by engagement ofthe coupling sleeve 20 with thewasher 23 resting on the upper one'of the bearings;21.

The shaft 19 is provided with a pulley 24; f

I 9Ov which is driven by a belt 25..

The companion bowls on the same side of the table are driven by the samebelt 25' which passes' around the pulleys 24 associated with these bowlsand also around a oneabove the'other and connected with a.

main driving pulley.27, this main driving pulley and-the two"intermediate driving pulleys 26 being mounted on a depending arbor 28secureduto the underside of the main frame about midwaybetween the twopairs ofbowls.- I 1 if Although any suitable means may be em ployed fordriving thev main pulley,,that shown in the'i drawing's is preferred andconsists of an electric motor 29 mounted on the floor and providedwitha-driving pulley' 80, Y

and 'a' drivingfbelt 31 passing-around the pulleys 30 and 27 and-alsoaround intermediate guide pulleys 32 which are mounted on themainrframe.I i a Across the upper end of each bowl is arranged a cleaning cloth 83which is of coarse or open mesh, such for instance as ordinary burlap,which Wlll permit a cleaning fluid,

such as water or a mixture of water and grit or sand together with any.dirt removed from the eggs to pass from the inner or upper side of thewashing cloth to the inner side of the bowl. In the preferredorganization, this washing cloth is preferably mounted on the upper endof the bowl so as to form aidownwardly hanging sack or bag within thebowl as shown in Fig. 4. In order to permit of readily: renewing thiswashingcloth when the same becomes worn,

- means are provided for'detachably securing -the same to the bowl. Asuitable means for fastening the wash cloth to the bowl is shown in Fig.4 andthe same consists in providing the marginal portion or edge of thewash cloth with a downwardly projecting-flange or flap 34*which isclamped between an external screw thread v35 formed onthe upper edge ofthe bowl and an internal'screw threaded clamping ring 3,6 engaging withthe outer side of this flap. In or- L= der to limit the downward motionof this clamping ring and increase the clamping effect of the same withreference to the cloth, the upper edge of'thi's ring is pro vided withan inwardly projecting annular flange 37 which engages with the washcloth 7 above the upper edge of they bowl, as shown in Fig. 4. Y V

38 represents a. delivery pipe which is arranged below a table top andterminates at its outer end adjacentto the upper side of the bowl andwashingcloth. The two delivery pipes 38 on the same side of the ma-,.chinepreferably form branches ofa main delivery pipef39 whichcontains avalve 40 v for controlling the'supply of cleansing mate-;

rial and these two'delivery pipes are in turn connected with the 'mainsupply pipe 41 which receivesits supply from any suitable source.- 3 1 I7 Although any suitable'cleansing fluid may i be employed for thispurpose, it is'prefere of soapi able to employ water towhich hasbeenadded a suitable quantity of sand or other gritty} material and-also asuitable quantity At the lower end of each hollow shaft is arranged avalve 42 which permits of regulating the discharge of the wastecleansingliquid-0r materialfrom the bowl. IThe material dischargedthrough the several hollow waste pipes 19 is caught by a pan 43 whichissupported on the underside of the table top and is provided in itsbottom with V a waste pipe 44 leading to'the sewer orother placedesigned to receive the liquid which has been spent'in washing the eggs.

V 5 When the'machme'ls inoperation acleans i ing fluid is supplied byeach of the'delivery pipes 38 into the upper end of each washing cloth,while thelatter together with its bowl and associated parts are rotatingabout a vertical axis. The eggs to be cleaned are taken one at a time bythe operator and passed by one hand downwardly through the opening 12inthe table top and engaged which not only aids in removing the dirt fromthe egg but also causes the dirt to be carried through the openings ormesh of the cloth and into the interior of the bowl from which latterthe liquid escapes through.

the hollow shaft 19, valve 42, pan 43 and waste pipe 44 to the sewer.

By closing the valve42 more or less thees cape of the wash water.orliquid fromthe bowl can be regulated so as to maintain the level ofthe liquid in the bowl at such a height that the lowermost part of thecloth-- wash bag therein will be submerged in the cleansing liquid andthus facilitate the sof-y tening of the dirt on the eggs andpromote andexpedite the cleaning of the same, this being particularly desirablewhen the eggs" are very dirty. e-

If city water pressure isv available the supply pipe 41. maybevconnected directly, therewith, but where such water supply is notavailable an overhead supply tank45 be provided, the bottom of which isconnected withithe supply pipe 41 and thus causes'the cleansing water toflow by gravity from the tankto the several wash bowls, as shown in Fig.2. 1 v f The machine is very simple in construction, it can be producedat comparatively low cost and Op rated with a minimum expenditure ofpower and effect its cleaning with a moderateamount ofj,water, and it.

permits of cleaning eggs easily, conveniently and ex editiously, sothata comparatively large number of eggs can be cleaned in acomparatively short time.
